Brick Economy suggests a used Fero And Skermix is worth $55.76 USD! That’s more than double the MSRP of the sealed set, which they say is worth $142.39. If I had to sell my Fero And Skirmix, I’d get more profit than the interest my bank has paid me for the last 5 years!

This seller in the USA currently has one for $37.25 USD before shipping. Even after the shipping, it would still cost me less than the current market value. The seller does warn about different colored red pins, and certain red parts from this time being brittle, and asks you to check out the pictures before hand to make sure everything looks to be in order.

For those readers in the United Kingdom, this seller has one for GBP 19.99, which eBay suggests is about $27.00 USD. The shipping would cost me more than the set itself, but I imagine if your in the UK it will be much cheaper. The seller says the model is anatomically complete, but missing the projectile.
